Sugar ester peracid on site generator and formulator

摘要

Methods and systems for on-site generation of peracid chemistry, namely peroxycarboxylic acids and peroxycarboxylic acid forming compositions, are disclosed. In particular, an adjustable biocide formulator or generator system is designed for on-site generation of peroxycarboxylic acids and peroxycarboxylic acid forming compositions from sugar esters. Methods of using the in situ generated peroxycarboxylic acids and peroxycarboxylic acid forming compositions are also disclosed.

主权项

1. An adjustable biocide formulator or generator system for on-site peroxycarboxylic acid forming composition generation comprising:
an apparatus comprising at least one reaction vessel, a series of feed pumps, an outlet for dosing a peroxycarboxylic acid forming composition from said reaction vessel, and a control software; wherein said feed pumps are in fluid connection with said reaction vessel and supply reagents to produce said peroxycarboxylic acid forming composition in said reaction vessel; wherein said reagents comprise an ester of a polyhydric alcohol and a C1 to C18 carboxylic acid, a source of alkalinity and an oxidizing agent mixed in the apparatus at an alkaline pH above at least 12; wherein said reaction vessel is in fluid connection with said outlet to dispense said peroxycarboxylic acid forming composition; wherein said peroxycarboxylic acid forming composition is diluted with an acid or aqueous acidic solution to form a peroxycarboxylic acid; wherein said peroxycarboxylic acid forming composition is an individual or mixed peroxycarboxylic acid forming composition according to a user- or system-inputted selection; and wherein said user—or system-inputted selection is controlled by said control software for said on-site generation of said peroxycarboxylic acid forming composition, and wherein said user—or system-inputted selection is an individual or mixed peroxycarboxylic acid forming composition and corresponding volume or mass for said on-site generation.
